SAMUEL ORUMP, OF POUGHKEEPSIE, NEW YORK, ASSIGNOR TO PRINTERS ROLLER WASHING MACHINE COMPANY, OF NEW YORK, N. Y.

MACHINE FOR CLEANING PRINTERS ROLLERS.

SPECIFICATION forming part of Letters Patent No. 696,134, dated March 25, 1902.

Application led November 26, 1961. Serial No. 83,715. (No model.)

T0 all whom, zit may concern:

Be it known that I, SAMUEL ORUMP, a citizen of the United States, and a resident 'of Poughkeepsie, in the county of Dutchess and State of New York, have invented new and useful Improvements in Machines for Cleaning Printers Rollers, of which the following is a specification. Y

This invention relates to a machine for cleaning printers rollers by means of a suitable solvent or cleansing liquid which is applied to the roller under treatment and whereby the ink and other adhering matters are loosened, so that they can be removed by a scraping or other cleaning device which actsupon the roller covered with the cleaning liquid or solvent.

The object'of my invention is to produce a machine for this purpose which is simple inconstruction,which removes the ink and other adhering matters quickly and thoroughly from the roller under treatment, which cleans leather-covered rollers Without injury to the longitudinal seam of the leather cover, which produces a soft or napped surfaceon leathercovered rollers, which operates upon rollers of different diameters without requiring adjustment of the parts, and which possesses other advantages.

My improved machine in its most complete form comprises, briefly stated, rotary supports between which theprinters roller to be cleaned is clamped and bywhich it is rotated, rubbing-rollers which apply the solvent or cleansing liquid to the rotating roller` and work the liquid into the surface thereof, a

scraping or wiping device by which the layer of solvent, ink, and other matters covering the roller is removed therefrom, a traveling carriage in which the cleaning-roller, the scraping or wiping device, and other instruinentalities operating upon the roller are mounted and whichis moved lengthwise of the rotating roller, so as to move these instrumentalities along the cylindrical surface of the same, a cleaner-disk, which is also mounted in said carriage and which acts with its iiat working face against the roller, and an annular stripper, which is also mounted in said carriage and which surrounds the roller and removes any remaining liquid and impurities therefrom.

Like letters of reference refer to like parts in the several gures.

The main frame of the machine may be constructed in any suitable manner. As shown in the drawings, it consists of two upright end frames A A, two upper longitudinal connecting-bars a a', and a lower connectingbar a2. This frame contains two horizontal spindles, between which the roller to be cleaned is clamped and by which such roller is rotatedaboutitsaxis. Thesespindlesmaybe constructed and arranged in any suitable manner, the arrangement shown in the drawings being as follows:

B represents the live-spindle. (Best shown in Figs. l, 2, and 3.) This spindle is journaled in bearings a3 a", formed, respectively, on the end frame A and on a bracket a5, secured to this end frame. This spindle is rotated by a tight pulley b and a belt b.

b2 is a loose pulley, which is arranged on the outer side of the tight pulley.

C represents the printers roller to be cleaned, and c the journals thereof.

D represents the dead-spindle, which is arranged at the opposite end of the machine on a longitudinally-adjustable support D'.

The live-spindle is provided at its inner end with a socket-piece b3 for the reception of one of the roller-journals c and the dead-spindle with a socket-piece D2 for the reception ofthe other roller-journal. The socket-piece D2 is free to turn in the end of the dead-spindle D, and a suitable antifriction or ball bearing d may be interposed between the socket-piece and the end ofthe spindle,as indicated in Fig. 3. The socket-piece b3 of the live-spindle is split, as shown at b4 in Figs. 2l and 22, and its outer surface is conical to fit the conical socket at the inner end of the spindle, so that when the journal of the roller is pushed into this socket-piece the separated parts or jaws of the latter will grasp the journal firmly and com pel the roller to turn with the socket-piece and the spindle. Any other suitable means for compelling the roller to turn with the livespindle may, however, be employed. The socket-piece b3 is provided with a stern b5, which extends axially through the spindle B and beyond the outer end of the latter, as shown in Fig. 3. The socket-piece is rotated with the spindle by the frictional contact of the parts and is released from the spindle when the roller is to be removed by pressing the socket-piece b3 away from the tapering socket of the spindle. This pressure is conveniently applied by an elbow-lever b, pivoted to the bracket as and bearing with its upper arm against the outer end of the stem b5 of the socket-piece and having its lower arm connected by a rodb7 to a treadle bg, arranged in the lower portion of the machine, Figs. 1 and 19. By depressing this treadle the tapering socket-piece Z13 is loosened in the tapering socket, so that the sections or jaws of the socket-piece can spread apart and release the roller-journal. The live-spindle is heldagainstlongitudinaldisplacement byany suitable means-forinstanee, as shown in Fig. S-against movement in one direction by the hub of the fixed pulley b and the bearing a3, and against movement in the opposite direction by a shoulder on the spindle bearing against the bearing a4.

The adjustable support D' ot the dead-spindle D is mounted on the upper front and rear bars a a' of the frame in such manner that it can be adjusted toward and from the livespindle as the length ofthe roller to be cleaned may require. Any suitable device for locking the spindle-support in its adj usted position may be employed. The locking device which is shown in the drawings, particularly Figs. l, 2, 3, and 20, is constructed as follows:

The spindle-support D' is provided with sleeves d d2 d3 d4, by which it is supported and guided on the frame-bars a a. The sleeve d3, which embraces the rear bar a and is arranged nearest the end frame A', is provided on its under side with a vertical locking-bolt d5, Fig. 20, which bolt is vertically movable in the sleeve, so that it can be pressed against the under side of the frame-bar a for holding the spindle-support in position on 4the latter and can be released when the spindlesupport is to be moved on the frame-bars. This locking-bolt is applied and released by a horizontal lever d6, which bears with its short rear arm against the-under side of the bolt. This lever is pivoted by a horizontal pivot dT to a head d8, which is connected by a vertical pivot d to the spindle-support D in front of the sleeve (Z3. This vertical pivot Z9 is preferably provided above the spindlesupport with a spring d10 and a nut d,where by the head d8, carrying the lever d, is supported and enabled to yield downwardly. The short rear arm of the lever d has the form of a Iiat segment-shaped head, (shown in dotted lines in Fig. 2,) so that the rear arm of the lever remains in contact with and supports the locking-bolt in the various positions of the lever. The latter is held in its adjusted position by a locking-segment d, which is provided on its under side with ratchet-teeth having their abrupt faces turned toward the live-spindle, so that the lever is held by engaging against the abrupt faceof one of the teeth.

(Z13 is a guide-bar which extends horizontally below the segment and the lever and upwardly in rear of the segment and horizontally over the rear portion of the segment and which confines the lever near the segment.

To release the spindle-support D', the front arxn of the lever d is depressed to disengage it from the segment, and the lever is swung IOO rearwardlybeyond the segment and up over the rear portion of the segment. This releases the locking-bolt d5 and allows theV spindlesupport to beshifted on theframe-bars. Assuming that a printers roller to be cleaned hasbeen engaged with onev of its journals in the socket-piece b3 of the live-spindle, the spindle-support D isnow moved on the supporting frame-bars toward the live-spindle until the other journal of the roller isengaged inl the socket-piece D2 of the dead-spindle. The lever dbears against the rear end of the deadspindle,preferably by means of a springpressed bolt du, Fig. 3, seated'invthe spindle, and is swung with its front end toward the live-spindle to tighten theroller-journals inl the socket-pieces of thespindlesI and is `interlocked with the segment when; the roller has been clamped to.y the spindles. The same tightening movementof the lever also tight.- ens the locking-bolt d5, whereby the spindlesupport D is secured in position.

, E is a traveling carriage, which is movableV on the stationary frame of the machine in' a direction parallel to the axis of the roller toV ticularlyFigs. l to 7 and 1:9, is constructed asV follows:

v The carriageis composed ofa longitudinal rear` sleeve e, which slideson the rear,frame bar a',.and two forwardly-projecting arms e e2, which are provided at their front ends with sleeves e?? e4, respectively, which slideonthe front frame-bar a.

frepresents a traveling endless chain,which is arranged in the vertical frame lengthwise on the rear side ,of the machine and which runs around a driving.sprocket-wheelrF and adriven sprocket-wheel F. The upper and lower reaches or stretches of the chain are supported by upperl vand lower channeled guides f f2, preferably `formed on a light f rame f3, which is secured to the stationary main frame. A coupling device is `provided on the carriage -forattaching it tothe upper or lower stretch ofthe chain, forA moving the carriage in one orthe other direction, `or for disconnecting the carriage lfrom Ythe chain when no movement of the carriage isrequired. This couplingr deviceis best shown in Figs. 4to '7 andconsists of a'shortV coupling-.bolt

f4 for connection with the upper reach of the. chain and a long coupling-bolt f5 for connec-' tion with the lower reach, bothconnected. to

a rock-leverf,,secured1 to the rear ,end of aV horizontal shaft f7, which extends forwardly over thecarriage andcis provided at the is in engagement with the upper reach of the,

l chain, which travels in the directionindicated by the arrow to the right in that figure orto- -Figs. 4, 5, 6, and 9..

ward the live-spindle,vand the carriage is therefore moved forwardly or towardthe live,- spindle. vThe long bolt fis-out of engage! ment with the lower reach of the chain. Upon reversing the rock-lever f6 the long bolt .can be engaged with the chain and the short bolt disengaged therefrom for returning the carriage, and by placing the rock-lever in the intermediate horizontal position both bolts are disengaged, from the chain and the carriage remains at rest. The chain is driven from the live-,spindle Vby any suitable means, andi the driving mechanism of the machineis preferably so arranged that the carriage can be propelled while the roller to be cleaned is beingrotated and. alsolwhile the roller is at rest. Asshown in the drawings, (Figs. 1, 2, and/3,) the driving mechanism is constructed as follows: l

gis a worm which engages with a wormwheel g'on the shaft gzof the driving sprocketwheel F. This worm is loosely mounted on the spindle, and provided at opposite ends with clutch-faces g3 g4, the face gSlbeing, adapted to engage .with a clutch-face g5 on the outer end of the live-spindle andtheface gwith a clutch-faceg6 on the hub ofthe loose pulley b2. The worm is attached to the live-spindle, so as ,to hold'the clutch-faces g3 and g5 in engagement, by any suitable fastening deviceforA instance, ascrew gl, which engages vin a holeV g8, formed in the live-spindle, Figs. 3 and 23. For disconnecting the worm from* thek spindle the kscrew is withdrawn and the worm isl shifted so,as to be engaged by its ,clutchface g'witlithe clutch-face g5 Aof the lo'o'se pulley 192.and ,the screw is vengaged inan an-` nular groovegZFig. 23, formed inthe spins die.` This groove holds the'worm in engage# ment with the loose pulleyand permits the wormfto rotatefreelyonthe spindle. ,When the roller isto be rotated and the-carriageis to be driven by the chain, the wormis coupled withthe live-spin,dle,asv described, andthe belt is shifted to the 'tight pulley. When the roller is to remain stationarywh'ile the carriage is-'moved lby. the chain, the worm is coupled with the, loose pulley and the belt is shifted to the latter. The machine isstopped bystopping the shaft from which the machine isdriven and which is not shown in the` drawings. 1 ,H H' represent rubbing-rollers, which Vare arranged in vthe traveling carriage so as Yto bearagainst Ythelower rearfside. of the roller to be cleaned, and ,which are preferably -rotatedby contact with the roller. of these rollers are arranged side by side upon a fixed shaft h, so as toturn freely thereon, The rollers H are grooved orfrihbed on theirl peripheral faces and alternatev with thesmooth-facedrollers H. vThe grooves or ribsnon the rollers H yare preferably arranged vobliquely and in opposite directions on alternate grooved rollers, as indi' cated inFigs. 2 and 4, so that the ink on the printers roller is cut first in'one direction IOO IIO

and then in another. At each end of the series of rubbing-rollers there is arranged upon the shaft h a tapering roller 112 for the purpose of guiding the rubbing-rollers to the surface of the roller to be cleaned. The shaft ZzI is secured in the lower ends of two pendent arms Zt', which are arranged against opposite ends of the rear sleeve e of lthe carriage, Figs. 4, 5, and 9, and are hung loosely on the rear frame-bar d. The upper portions of the arms Zt are rigidly connected by a horizontal rod or bar 71,3, so that the two arms h', the shaft ZL on which the rollers are mounted, and the connecting-bar h3 form a rigid frame, which is hung loosely on the frame-bar a'. The rubbing-rollers, arranged in the lower portion of this frame, can swing forwardly or y backwardly and are carried back and forth in the stationary frame -by the traveling carriage.

I represents a shallow receptacle for the solvent or other cleansing liquid which is applied to the printers roller to be cleaned. This receptacle is arranged below the rubbing-rollers and is loosely hung on the rollershaft ZL by ears arranged between the end rollers and the arms 72,', as shown most clearly in Figs. 5, G, and 9. This receptacle has the form of an open-topped four-sided box, and the rollers H H are so arranged in the same that they dip into the liquid contained therein and elevate the liquid and apply it to the printers roller to be cleaned. This receptacle I is supplied with liquid in any suitable manner, but preferably from a reservoir I, which discharges the liquid from its lower end at Z, Fig. 6, into a receiver l2, from which the liquid passes by a horizontal pipe yZ to the receptacle I. This reservoir I is of the wellknown type which is used as the oil-reservoir of students lamps and maintains the liquidlevel automatically at the proper height in the receptacle I. The reservoir l is supported by a lever K, which is pivoted upon the front bar a, of the frame and has its lower arm k arranged parallel with the arms Zi/ and pivotally connected to a clip Zo", embracing the front portion of the pipe t", so that the arms 7a and h and the pipe t and reservoir I can swing back and forth on the frame-bars a a as the rubbing-rollers lI H/ adapt themselves to the diameter of the printers roller C under treatment, which may be greater or less, as such printers rollers are usually made of standard sizes ranging from two to three and a half inches in diameter. The upper arm 7.32 of the lever 7.: extends rearwardly and is provided with a weight 7f3, which overbalances the weight of the reservoir I' and contents and the rubbing-rollers H H and connecting parts and presses the rubbing-rollers against the printers roller. The hanger-arms Z1 and the lever-arm Zt, hung loosely upon the fixed frame-bars a a and connected by pivotal joints with the receptacle I and the pipe li', respectively, form a parallelogram having its upper side fixed by the frame-bars a a and its lower side movable forwardly and upwardly and backwardly and downwardly, whereby the pipe "i" and the receptacle I are maintained in their normal horizontal position and the reservoir I in a vertical position in the different positions of the rubbingrollers. l

L, Figs. 4, 5, 6, l0, and ll, represents a wiper, scraper, or cleaner which is mounted in the front portion of the carriage and which is pressed against the lower front side of the printers roller for removing therefrom the film of liquid, ink, and otherimpurities. This wiper is secured to a depending arm Z of a lever L', which is mounted loosely on the front frame-bar a within the carriage. The wiperarm Z is arranged centrally in the carriage, Figs. and 5, and is formed on a long hub Z' of the lever. This hub is arranged on the front frame-bar a, between the arm Zr, of the lever K and the sleeve @4 of the carriage. The leverL' is provided with a forwardly-extending arm Z2, which is arranged adjacent to the sleeve e4 of the carriage and provided with a weight Z3, by which the wiper is pressed rearwardly and against the printers roller. The wiper may be held out of its working position when not required for use by any suitable means-for instance, bya hook Z4, Figs. 2, 5, G, and 2l, which is pivoted to the arm e2 of the carriage and engages over a rearwardlyprojecting arm Z5, formed on the hub Z adjacent to the arm c2. its lower end with a tailpiece Z, which is struck by the arm Z5 as the latter is swung down and which swings the hook over the arm, so as to engage therewith. Before the wiper reaches the printers roller under treatment as the carriage moves forwardly the wiper is held out of engagement by this hook, and when the wiper has passed the front end of the roller the hook is released and the wiper is swung against the roller by the overhanging weight Z3.

The working face of the wiper or scraper L may be constructed in various ways, depending somewhat upon the nature of the rollers which are to be cleaned. A very satisfactory construction of the working face is that shown in Figs. 10 and ll, and consists of thin blades of suitable metal Z7, which are secured to a back plate Zsso as to project edgewise therefrom. These blades are preferably arranged obliquely and on opposite sides of the centralV line of the wiper in opposite directions, as shown, and impinge with their edges against the roller. The blades are conveniently secured to the back plate by being bent to an angular form, so that each blade is provided with a base-flange, as shown. in Fig. l1, which flange is secured to the back plate by an overlying strip Z. The Wiperblades being arranged obliquely and in opposite directions work first one way and then another, whereby all depressions and imperfections in the surface of the roller are thor- As [the blades are a1'- oughly cleaned out.

This hook is provided at IIO ranged obliquely, they intersectl the longitudinal seam of a leather-covered roller at an angle, whereby injury to the same is prevented. This scraper orvwiper removes the lilm of -turpentine orlother cleansing-liquid without reducing the same to fine particles or atomizing the same, whereby the'genera- `tion of iniiammable vapor during the operation -of the machine is avoided.

M represents a disk-shaped cleaner, which is arranged to bear with its fiat face against the roller to be cleaned. This cleaner is sev cured to the end of a rotary spindle or shaft m, which is preferably arranged vertically above the'roller to be cleaned. As shown in the drawings, Figsfl to 3, the spindle mof this cleaner is driven by a pulley m', having a downwardly-extending hub m2, which is journaled inabearing m3, formed at the upper end of an arm m4; Thelatter is secured upon the arm e'of the carriage E, which is nearest the live-spindle.- The vertical spindle m is so connected with the hub of this pulley that the spindle-while being driven from the pulleyis free tomove up or down in the same as the size of the printers roller may requirefupon which the cleaner-disk bears. For this .purpose the hub of the pulley is provided in its bore with a driving projection-or key m5, Fig. 25, which projects into a key-y way m6` in the spindle, Figs. 3 and 25. The pulley isheld in the bearing m3 against vertical displacement by any suitable meansfor instance, by a screw m7, Fig. `3,.secured in the bearingand projectinginto al1-annular groove ms inthe hub of the pulley. The pulley is driven by any suitablemeansin such a way that the spindleV is rotated-while the carriage is moved back and forth on the stationary frame. Themechanism shown for thispurpose in ther drawings is constructed as follows: n is an upright shaft, which is journaled in a bearing n, secured to the end frame A over the live-spindle and driven at its lower end from the latter by bevel-wheels n2 n3. n4 is a horizontal driving-pulley,which is secured to the upper end of this shaft and around which the driving band,belt, or cord m5 passes. This band -passes from the driving-pulley n4 around the rear side of-.the pulley m and forwardly around aA guide-pulley n, mounted upon the front portion ofthe carriage, then to the opposite end of the machine and around a guide-pulley 117, mounted thereon, and then back to the driving-pulley n.4. The at working face of this rotary cleanerdisk-may be constructed in various Ways-for instance, if this cleaner is intended to work on leather-covered printers rollers the working face may be constructed'of card-clothing having sharp teeth which act upon the leather surface in such a way as to produce a soft, chamois-like, or napped surface. This rotary cleaner-disk also removes from the printers roller the remaining adhering foreign matter-such as `traces of ink, paperrber,

dac-an d tends to reduce the roller to uniform diameter when the roller has become uneven by hard spots formed on its surface or other- Wise. By subjecting the roller to al mechanical abrading device of this kind the surface of the roller is rendered more uniform. In some cases the fiat working face of the rotary cleaner may be composed of sandpaper or similar abrading material orofY card-clothing provided with flat-ended or dull teili. The flat working face of this abrading or cleaner disk operates on opposite sides of its axis upon the printers roller in opposite directions, Whereby the surface of the roller is rst worked in one direction and then inthe opposite direction. This intensities the action of the disk materially and greatly improves the condition'of the :surface of the roller. When the spindle of the cleaner-disk is arranged vertically, as shown in the drawings, the disk rests upon the roller by gravity.

O represents an annular stripper, which is attached to the traveling carriage and arranged transversely to the axis of the roller to be cleaned, so that this stripper surrounds the roller and bears upon the surface thereof in being moved with the carriage-lengthwise over Vthe roller. This strippen-.may be employed for removing from the surface of the roller any traces of liquid, ink, or other adhering mattei'. This stripper, which is indicated in Figs. 1 to 3 andshown most clearly in Figs. 12 to 17, is constructed as follows:

O/ represents an annular frame, which is secured tothe carriage E at one end thereof and which depends below the carriage in such a position that Athe center of this annular frame is in line with the axes of the spindles BandD.v f v O2 represents an annular series of stripperblades,-Which are each pivoted atv one end by a pivot O3 tothe annu-lar frame O' and which have their inner or Working faces O4 `preferably so shaped that different portions of each face will correspond in concavity with the curvature of the different standard sizes of printersrollers which -are to be cleaned. For instance, as indicated in Fig. 18,- the inner stripping-face of the blade is composed of fourconcavesections of progressively larger'. radius from the outer tothe pivoted end of the blade. These blades are closed against the-roller operated upon bya ring O5, which is arranged within the annular frame O and which engages with the annular series of stripper-blades by any suitable means-for instance, as shown in-Figs. 15 to 18, by notches O6, 4formed in the inner edge of the ring and engaging with pins OT; one of which is formed on the heel of each blade near the stripping edge thereof. vThe ring O5 is turned in the proper direction for tight- ICO IIO

eningthese blades against the roller by a` completely surrounds the roller, all liquid and other matterl adhering to the roller are driven before the stripper until the end of the roller is reached` P represents a trough arranged lengthwise between the end frames A A/ underneath the carriage for receiving the liquid, ink, and other impurities which are removed from the printers roller. This trough is provided with a waste-pipe p for discharging this material into a bucket.

The printers roller is cleaned by clamping it between the spindles, so as to be rotated, and causing the carriage to travel along the roller once or several times, as the condition of the roller may require. During this movement of the carriage the rubbing-rollersHH apply the cleaning liquid to the roller and cut up the ink and other impurities on the roller and rub or work the cleansing liquid into the surface of the printers roller. The scraper or wiper L removes the loosened layer of material from the surface of the roller, and the cleaner-disk finishes the surface. Then the roller has been so cleaned and it is desired to remove from the roller any traces of liquid, ink, or other adhering matter by means of the annular stripper, the live-spindle is disconnected from the worm and the carriage is moved along the roller without turning the latter, the scraper L being supported by the hook Z4 out ot its working position and the cleaner-disk being supported clear of the roller by any suitable means. The blades of the annular stripper bear against the roller all around the same during this movement of the carriage and remove any remaining traces of adhering matter. Vhen the scraper L and the cleanerdisk M are in operation, the annular stripper is held open, so as not to bear upon the roller by any suitable means-for instance, by supporting the weighted arm O8 by a removable pin O1", secured to the annular frame O'.

The mechanical construction of the parts of this machine can be modified in many respects without materially changing the general organization and the operation of the same.
